I'm new to using sql so I'm having difficulties (and worries) in adding a new column of data to a table I have. Its a very large file (around 5 Gb) which is why I'm having to use SQL I have a table with variables ID, IDrec and IDdes and the variables IDrec and IDdes give a mapping of some other values but the other values are associated with the ID variable (think of IDrec and IDdes

Grothendieck Version: R version 2.1.0, 2005-05-14 OS: Windows XP Submission from: (NULL) (216.59.254.207) This code: > plot(1:10) > text(5,5,lab=expression(italic(22*"33"))) has the effect of italicizing 33 (which is a character string) but not 22 (which is not). I would have thought that both, not just 33, would be italicized. I had previously posted about this

I would like to know if a MetaPost device is available or in the plans. A search MetaPost in the documents and list archives did not turn up anything. [I would prefer to use MetaPost when the graphics is to be included in a document that I want in both hard-copy and in pdf formats.] If not, how easy/hard is it to add a new device to R? I caouln't see anything about adding devices in the

I'm trying to combine multi-line text and math annotations on a plot and am not having much luck. I looked at various suggestions in the archives, but I cannot coerce any of them to do what I want. I'm beginning (finally?!) to think that there is an entirely better approach than the one I have tried. The essential problem is that line breaks (\n) don't seem to behave the way I

Full_Name: Wolfgang Huber Version: R-2.0.1 OS: HP-UX B.11.23 ia64 Submission from: (NULL) (81.104.215.6) Hi, I hope I am not missing something basic... I am using a somewhat exotic compiler and OS, but if I understand what I am seeing the problem is more general: In src/main/plotmath.c, the following function is defined /* Thickness of rules */ static double RuleThickness() { return

This is a followup to a recent post on using atop() to obtain multiline expressions. My reading of the plotmath docs makes it clear that issuing (in base graphics) the specification par(cex = 2) doubles symbols and regular text in subsequent plotmath expressions. However, it is unclear to me what specifying cex _within_ the annotation function using plotmath should do, and the following seems

Is there a hook that allows a graphics device to apply transformations to plotmath expressions *before* they are rendered? If there isn't one yet, would it be feasible to add one? The motivation for this hook is graphic devices that feed into something that already has support for math layout, such as the tikzDevice package (which has TeX downstream). Given text(x, y,

I'm using R-2.6.2 on Fedora Linux 9. I've been experimenting with plotmath. I wish it were easier to combine expressions in plotmath with values from the R program itself. There are two parameters in the following example, the mean "mymean" and standard deviation "mystd". I am able to use bquote to write elements into the graph title like mu = mymean and R will

Full_Name: Murray H Smith Version: 1.7.1 OS: Windows2000 Submission from: (NULL) (202.36.29.1) This alleged bug is Windows specific and occurs when using Windows metafile plots. The problem does not occur in a Linux version. It does not occur in the pt rintout when a graphic is saved to a postscript file under Windows. The problem came to light when using plotmath to label a plot with

sorry, I forgot my sessionInfo: please see below. -------- Original Message -------- Subject: puzzled with plotmath Date: Thu, 20 Jan 2011 12:48:18 +0100 From: Claudia Beleites <cbeleites at units.it> To: R Help <r-help at r-project.org> Dear all, I'm puzzled with matrix indices in plotmath. I'm plotting matrix elements: Z [i, i], and I'd like to put that as label.

I hope to use the plotmath facility to print titles that mix math and values of R variables. The help for "plotmath" has an example, which after repeated reading, I find baffling. Likewise, I have read the help file for "substitute" (wqhich seems to be needed) without ever understanding what it does, other than being used in some magic incantations. I would like to do

Is it possible to use the '\ell' (i.e. the log likelihood) in plots? I've been browsing the plotmath documentation unsucesfully.

hi there, I find the following codes produce strange output. plot(1:10, xlab = expression(NO[3]^-~(mg/L))) you will notice that the unit, mg/L is in superscript format. That means that "~" is not for space. However, the help page of plotmath does not mention this behavior. Best, Jinsong [[alternative HTML version deleted]]

I am interested to use plotmath functions within a panel function but am having some problems getting the code right. Within each panel I am plotting the data, fitting a regression line, and would like to print the regression equation. Here is a trivial example of what I'd like to do: # generate simple data tmp.df <- data.frame(id = rep(1:4, each=4), time = rep(1:4, 4), das =

There's something (probably a lot) missing in my understanding of plotmath. The LaTeX code for what I'm trying to produce is \log(-\log(\hat R)) My (probably hopeless) attempt at it uses nested group()s: expression(plain(log) * group("(", -plain(log)*group("(", \hat(R), ")"), ")")) Can anyone do it right for me, please? Thanks, Ted. Dr E.A.

Recent questions about using plotmath have renewed my interest in this question I want to have expressions take values of variables from the environment. I am able to use expressions, and I am able to use paste to put text and values of variables into plots. But the two things just won't work together. Here is some example code that shows what I mean. plot(NA,xlim=c(0,100),ylim=c(0,100))

I've been testing plotmath. But I'm getting some funny output one one computer. The problem is that characters are 'jumbled' and overstrike when symbols are introduced. Sample code: mu <- 440.0 sigma <- 12.5 myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500) myDensity <- dnorm(myx,mean=mu,sd=sigma) # Here's one way to retrieve the values of mu and sigma and

Folks: delta <- 1:5 I would like to put 5 separate lines of text of the form "10 %+-% delta[i]" into a lattice key legend, where ""%+-%" is the plotmath plus/minus symbol and delta[i] is the ith value of delta. The construct: lapply(delta,function(d)bquote(10%+-%.(d))) appears to produce a list of expressions of the correct form, and, indeed, if I assign the above
